ROTARY SIGN.

' Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed August 6, 1907.' Serial No. 387,323. i

. Be it known that I, PAULO. PETERS, a

citizen of the United States, residing at Juneau, in the county of Dodge and State of Wisconsin, have invented-certain new and useful Improvements in Rotary Signs, of which the following is a specification.

This invention relates to revoluble signs;

and the object of the invention is to provide a sign of the above character having a plurality of faces which is operable by the wind, or other means, and whereby, when similar letters or figures are delineated on the several faces of the sign in the same horizontal plane, said letters or figures will be discernible to the eye in a complete and permanent manner, at any radial point adjacent to said s1gn. a

A; further object consists in providin a sign with a plurality of advertising disp ay faces arranged with relation to one another so that when similar characters are similarly placed upon each face, all the letters in the same horizontal plane will appear to merge into a single letter.

A further object consists in a sign of-the above character, comprising a single piece of material having only one seam, thereby making it simple, strong, and cheap to manufacture.

I accomplish the objects of my invention by the revoluble sign illustrated in the accomplanying drawings, forming a part hereof,

in w ich Figure 1 is a side elevation of my improved revoluble sign, and showing the brackets for supporting same. Fig. 2 is a transverse section of the sign on the line 22 in Fig: 1. Fig. 3 is a fragmentary detail view in section, on an enlarged scale, of the rivets 21 which provide the contact points for the supporting pins, to support the sign.

The main body of my revoluble sign comprises a single piece of suitable material 10, which is so bent as to present a plurality of faces whereon advertising matter is displayed. Theprojecting points of the several edges of the slgn-faces project radially a like distance from the axis and are arranged at an equi-distance around the circle formed.

Examining Fig. 20f the drawings, it will be seen that the several faces of the sign are all bent alike on an 0 cc, or reverse curve, each face having a u orm surface area exwhich engages'a rivet'21 posed to the wind to cause the sign to run smoothly.

It will readily be seen that the concave portions of the sign-faces will catch the wind while the convex portions will have less 11esistance, whereby the'sign is caused to Wl'llIl or rotate.

As before stated, the revoluble sign is provided with a plurality of faces, and, in the drawings, I have limited the number to three which I consider the most desirable, from the fact that there is less interruption in the visionary effect than with .a sign havingmore faces and consequentlymore divisions or projecting points to cause such interruption. It will be noticed, in the peculiar construction of my sign, that the projecting edges are extremely thin, and that the letters or characters may be placed upon the faces so as to extend to the edges if desired, so that, stand- ,ing some distance away from the sign, the

characters in a given plane on the several faces so far as it is discernible, appear to merge into one, so that a single, permanent and complete image of only one set of the characters is presented in a permanent manner at any angle. I

The body 10 is generally provided with the endlates 12, so that the fulleffect of the wind is secured by preventing any loss or dissipation, in a longltudinal direction, over the ends of the sign-faces were these plates not present. The lates 12' may be provided with the annular s oulders 13, if desired, to strengthen said plates and add rigidity to the sign-body 10.

The sign, for exhibiting advertising .matter for outside purposes, is usually placed on the exterior walls or corners of buildings where it will be exposed to the Wind, and the sign-body is held in position by means'of the brackets or arms 15 and 16. X The lower arm- 15 has its outer end bent u ward and terminates in a conicallysha e needleoint 20 located in t e longi tudinal axis of the sign-body 10 and centrally of the end-plate 12. This rivet may be integrally or detachably formed of the plate 12, as desired. The plate 12 at the upper end of the sign-body is provided with a rivet 21 which is engaged by a vertically disposed pin 24 slidably mounted in the upper arm 16. A spring 25 surrounds the pin 24 and is interposed between the arm 16 and the transverse lurality of uniform sign-faces, a

pin 26 that passes through the vertical pin.

24. The spring 25 maintains a uniform pressure upon the vertical pin 24, is self adjusting and thus keeps the sign-body in position at curve, plates secured to the ends of said signbody and provided with right-angle rojecting annular flanges, and means for olding the sign-body in operable position.

2. A revoluble sign having a body formed of a single piece of material secured together at its 0 posite side edges and bent to provide a plura lty of uniform sign-faces, all of said faces being bent alike on an ogee or reverse curve, an arm provided with a needle-point toengage the sign-body at its longitudinal axis, an arm mounted above said sign-body, a center-pin adj ustably mounted in the 11 per arm and adapted to engage the longitu inal axis of the sign-body, and a yieldable tension means adapted to hold said center-pin into engagement with the sign-body.

3. A revoluble sign having a body formed of a single piece of material secured together at its opposite side edges and bent to provide a plura ty of uniform sign-faces, all of said faces being'bent alike on an ogee or reverse curve, lates secured to the ends of said signbody, dbtachable center-rivets located in the longitudinal axes of the sign-body and in the center of said end-plates, a fixed arm provided with a needleoint adapted to engage the lower detachab e center-rivet, an arm mounted above said sign-body, a center-pin adjustably mounted in the upper arm and adapted to engage the center-rivet in the upper end-plate, and a yieldable tension means adapted-to hold said center-pin into engagement with said center-rivet, to revent accidental displacement of said sign-libdy.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 29th day of July, A. D. one thousand nine hundred and seven.
